'Montereina' coerulescens is characterized by its mottled whitish-tan mantle with irregular greyish patches.
It has elevated rhinophoral sheaths, and yellowish-tan rhinophores. Distinctive are minute opaque white spots at the
mantle margin. The gills are translucent or translucent tan with whitish tips (in this picture and in 6 out of 9 pictures at the internet are the gills
retracted).
